He usually fights only with the same kind of fish. When he meets other kinds of fish, because of the long and beautiful big tail fin, fighting will slow down his swimming speed, but he may be bitten by local body scales. Therefore, it is suggested that betta be raised separately. Betta has a strong vitality and is easy to raise. Pay attention to the following points on weekdays: 1. You should avoid breeding in fast-flowing places, otherwise it is best to breed at lunch time in still water. 2. Avoid changing water frequently to avoid excessive temperature difference. 3. Avoid placing it in direct sunlight. If the site is limited and inevitable, it should also be properly shaded. 4. Do not directly impact the gill cover with water to avoid injury and "disorientation" of breathing. 5. Natural aquatic plants, such as water grass and water hibiscus, should be cultivated in aquariums or ponds to facilitate their reproduction and hiding. 6. During the breeding period, several other containers should be prepared, and aquatic plants should also be built in for health preservation, so that they can be transferred to small fish when necessary to isolate other bettas. 7. Avoid putting it in the same container with other kinds of fish, such as goldfish (killed by fighting fish without eyes) or carp (found that fighting fish accidentally broke into koi fish's mouth, leaving only half of its body) and so on. 8. Pay attention to whether the cultured water surface is covered with aquatic plants such as duckweed, and make sure that betta fish have room to breathe out of the water surface. 9. When feeding in a small container, pay attention to whether the betta fish is in danger of jumping out of the container when sticking out of the water for air. Betta is a very magical and beautiful species. When raising fighting fish, you often feel its unique charm. As long as you raise them carefully, they will certainly show you the most charming side.
